Phytoextraction of cadmium from soils treated with sewage sludge
Maxted, Andrew P. (2003) Phytoextraction of cadmium from soils treated with sewage sludge. PhD thesis, University of Nottingham.
The efficacy of phytoextraction strategies were tested by pot and field trials on soil contaminated with heavy metals, including Cd, derived from long-term disposal of sewage sludge. The strategies investigated were: i) the use of hyperaccumulators; ii) chemically-enhanced uptake using arable species and iii) the use of short rotation coppice (SRC). Chemical interventions including EDTA, chloride salts, HCl and herbicide were used to enhance uptake by arable and SRC species.
